JAMES CLARKE HAGEY, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE CABLE COMPANY, OF

I CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

TRACKER-BOARD AND MUSIC-SHEET.

Application filed July 11, 1911. Serial No. 637.971.

To all whom it may concern:

Be it known that I, JAa-rns C. HAGEY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, havelinvented a certain new and useful Improvement in Tracker-Boards and Music-Sheets, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming apart of this specification.

My invention relates to traveling sheet musical instruments, as for example piano players, player pianos and the like.-

My present invention relates more especially to the music sheet and tracker board arrangement of such instruments. It contemplates certain advantageous and desirable results as will be more fully set forth.

hereinafter.

In the accompanying drawings Figure 1 is a plan View of a music sheet and tracker board embodying my present invention; Fig. 2 is a similar view of a modification; Fig. 3 is a cross section of a tracker board of Fig. 1; and Fig/I is a longitudinal section of a tracker board of Fig. 2.

Referring first to Fig. 1, I show a tracker board 1, and a music sheet 2 traveling over the same. The tracker board 1 is provided with a series of ports 33 and a second series of ports H. The first named series of ports 3 3 are desirably longitudinally elongated, that is to say elongated longitudinally of the tracker board or lengthwise of the tracker board. The second series of ports 4-4 are preferably elongated transversely of the tracker board, and the second series are in the rear of the first series, port for port, and preferably the rear apertures or ports 44 are in the rear of one end of the corresponding front apertures 33. The music sheet 2 is provided with perforations 55 and 66. The perforations 5+5 are adapted to open one end or side of the front ports 33, and do not open the correspond ing or associatedrear ports 4-4:. The other perforations 6-6 are arranged and adapted to open-both the rear apertures 4--4 and the corresponding or associated front ports 3 3, passing over the ends-of the ports 33 in alinement with the ports 44.

The tracker may be used in any preferred or desired arrangement of instrument by connecting with the ports 3-3 and ea such Specification of Letters Patent.

mechanism as may be desired according to the result to be accomplished. It can be connected and used with mechanism such as disclosed, for example in patent to Harry Pierce N 0. 899,469. In such case the front apertures 3-3 would be connected with suitable mechanism for sounding notes, and the rear apertures 44 would be connected with.

suitable mechanism for modifying or changing the intensity of the notes to bring about solo or accent effects. By such mechanism the uncovering of ports 33 alone would cause soft or accompaniment notes to be struck, whereas the uncovering of both ports 3-3 and the associated ports H would cause solo notes to be produced, and thus by the use of my invention herein such solo and accompaniment effects can be produced by a music sheet 2 having perforations of the general character above set forth, which perforations it will be seen can be more or less of the same general character or'of more or less of a general narrow character as opposed to having some wide and some narrow perforations, wide ones for example for solo notes and narrow ones for accompaniment notes. It is not necessary,- of course, that the perforations should all be of the same character or Width because if desired they might be otherwise, but it will be seen that the invention permits all of the perforations to be more or less narrow, avoiding the need of wide perforations, and also permits all narrow perforations to be of the same kind if desired, it being only necessary to space them properly in the music sheet.

Of course the tracker board and music sheet of my invention can be used in any other way or with other mechanism than that referred to in said patent.

In Figs. 2 and 4 I have shown a modified form of tracker board and my improved music sheet with it. This tracker board 1 is provided with two ports 33, the ducts from which are united to form a single duct or channel 7 for each note. The tracker'is also provided with the rear ports H situated in the rear of one of the front ports 3. The music sheet,2 has the same kind of perforations as previously described, the perforations 5 opening one only of the ports 3 of apair, and the perforations 6 opening the other port of the pair, and the port 4 in the rear of the same.

It will be understood, of course, that zone, in combination with a tracker board having a plurality of ports for said individual note, one in the rear of another, said ports being partly in alinement in the direction of the music sheet movement, and partly out of such alinement, and one perforation being arranged to travel over the alined portions of said ports, and the other perforation being arranged to travel over the unalined portion of one of said ports, whereby one perforation will open both ports and the other perforation will open one port only.-

2. A music sheet having a plurality of perforations for an individual note, each perforation being of less width than the full tracker-board port space or zone for the note, and located on opposite sides of said tracker port space or zone, in combination with a trackerboard having a plurality of ports for said individual note, one in the rear of another, said ports being partly in alinement in the direction of the music sheet movement, and partly out of such alinement, and one perforation'being arranged to travel over the alined portions of said ports, and the other perforation being arranged to travel over the unalined portion of one of said orts, whereby one perforation will open both ports and the other perforation will open one port only.

3. A music sheet having a plurality of perforations for an individual note, said perforations being of the same width and each perforation being of less width than the full tracker-board port space or zonefor the note, and each occupying a different transverse position in said tracker port space or zone, in coinbination'with a tracker board having a plurality of ports for said individual note, one in the rear of another, said ports being partly in alinement in the direction of the music sheet movement, and

partly out of such alinement, and one perforation being arranged to travel over the alined portions of said ports, and the other perforation being arranged to travel over the unalined portion of one of said ports, whereby one, perforation will open both .ports and the other perforation will open one port only.

4. A music sheet having a plurality of perforations for an individual note, each of said perforations being of substantially half the Width of the tracker port space or zone for the note, and said perforations being located on opposite sides of said tracker port space or zone, in combination with a tracker board having a plurality of ports for said note, one in the rear .of

the other, said ports being partly in alinement in the direction of the music sheet movement, and partly out of such alinement, and one perforation being arranged to travel over the alined portions of said ports, and the other perforation being arranged to travel over the'unalined portion of one of said ports, whereby one perforation. will open both ports and the other perforation will open one port only.

5. A tracker having front andrear ports 'which are partly in alinement with one another in the direction that the music sheet travels, and partly out of alinement with one another, in combination with a music sheet having narrow perforations, some of which are so located as to open the alined portions of said ports and others of which are so located as to open only unalined portions of the same.

6. The combination of a tracker having longitudinally elongated front ports and transversely elongated rear ports, the latter being in alinement with a part or portion only of the front ports, and a music sheet having narrow perforations, some of which are located and adapted to open rear ports and alined portions of front ports, and others of which are located and adapted to open only the unalined portions of front ports.

7. The combination of a tracker havingsheet having narrow, perforations, some of which are adapted to open rear ports and the alined ends of front ports, and others of which are adapted to open only the other or unalined ends of front ports.
